So... I had a mini-epiphany. Popular bands/entertainers just fill empty holes. There's overlap and emptiness at times, but if there's a market there's a band/artist who will fill that hole (no matter how niche or strange it is, providing there is money there). It's actually kind of depressing. I do believe there was a set of musicians at some point who believed, without irony, that they had a certain obligation to the kids to live the life they spoke of in their songs.
